Control Key Standards

Identify Control Keys

The CA ADS dialog or application program that uses a map defines control keys for use with the map. If possible, the control keys available to a map operator should be documented by literal fields on a map. The operations performed by the control keys should also be documented for the operator.

When different terminals are available to terminal operators and control key names differ from keyboard to keyboard, each control key name should be documented so that operators do not have to memorize lists of key equivalencies.

Use Control Keys Consistently

Control keys should also be used consistently. For example, the same key should be used to take the operator to the next map in each application. A sample standard for control key usage is presented in the following table.
